I believe that you can.
Jerry

Yes you can. I have done mine in the about me section of my blog. Currently they are through my domain names, but after reading some training on linking, will be adjusting them slightly,to anchor text so they 'flow' as opposed to Go here ( if you get my drift

Yes I agree with Tony, you can Michael, in fact some of my sites are linked to each other.

Enjoy your day.

Roy

Yes Michael, You absolutely can my Friend!

Tony

I use the studio press themes for now.

I use the WA themes i don't use the paid themes can't afford it

I am using StudioPress themes at the moment. They suit my needs, are flexible and separate code from view. Am a programmer at heart and generally prefer to work with well-organised themes.

I only use paid themes. I use one theme for all my sites, and that theme gives me the flexibility to create various layouts and designs.

You can find free themes that are very good and will serve the purpose, and there is nothing wrong in using them.

But I have made the decision that my choice of theme is a business critical decision and I will have to rely on continuity, regular upgrades, security, and compliance to whatever change may happen in WP requirements.

So some years ago I got a license with my theme supplier and I now can use that theme on as many websites as I want, both for my self and for my clients.

Yes I am also using a paid theme as I wanted more flexibility.

But it all depends on your needs. Used a free theme for a long time, but at some point I just wanted to be able to adjust more website more.

Mikael

Yes, I have paid for themes Michael in the past and my Webmaster also has a few paid themes that he has given me to use. If you find the right theme, it is definitely worth it.

Enjoy your day.

Roy

I do.. I have a few premium themes but the one I find is the most flexibly is DIVI. If you would like to try it out let me know via pm...

Yes, I have paid for themes before and still, use them on some of my sites.

As far as which ones are the best, it depends on your needs.

I love my electronic gadgets and can't do without them so...just call them as they are...Must Have Electronic Gadgets.. : ).

I don't think that would hurt your SEO but I would do a review of your categories so your audiences would know the different categories so they can comment and ask you questions. That is just a suggestion though. I hope this helps you out.

I agree with Joe. I'd start off with one of those categories for your first site, then you can either add additional categories once you are established or build additional sites.

My opinion.

It's too broad. It is still possible to get ranked but you need a lot of content and SEO strategies to compete with other established sites. It is recommended to narrow it down to specific niche and targeting specific audience.

I can answer this for ShareASale and Awin.com. For both our networks you can do either. You can either put all of your site into one account or create a separate account for each site. The choice is yours. It all depends on how you want to organize your sites.

Hi Micheal, How are you doing? I will be using two affiliate programs on my web page. If am wrong someone yell. If you any other help, please me send a note. I am struggling with menus and widgets in WordPress at the moment. Is there a Wordpress book dummies LOL
your friend Sandy

No! You can create multiple sites for multiple niche in one account.
